This bag is serious. It is as durable as anything out there, like knife-stopping durable. Im not willing to stab my $100 dollar bag in order to prove myself right, but you get the idea. It is a great size for on day climbs and sport-climbing, and holds the essentials with ease. I got it on sale, but had I known what I know now, I would have easily paid full price for it. Its a great bag and I plan on using it for years to come.
